I assume some specifics have already been debated to death here. I know
that some specific features have already been pre-proposed here, proposed
and/or discussed. (importing enumerator names, importing all enumerators
from an enum, using name = expression) They all seemed to want to overload
the keyword "using" some way or another.

I have looked into the "using" token, and how it is used in C++17. It is
used to perform 4 duties :

   1.  *using qualified-name* to bring a name from another scope into the
   current scope.
   2. *using namespace ns* to bring all names of a namespace into the
   current scope.
   3. *using local-name = qualified-name* to alias a type with a new name
   in the local scope.
   4. *using superclass::superclass* to generate constructors from the ones
   in the superclass.

(I know that the word "scope" is improper and inaccurate. Sorry. Bear with
me please.)

If I want to extend these duties in the most general way, I would say that
"using" is used to :

   1. bring one name from a scope into the current scope.
   2. bring all names from a scope into the current scope.
   3. define a new name in the current scope that is a synonym of another
   name. (possibly from another scope)
   4. Not sure of what the last one is about. Anyway, this post is not
   about the using keyword.

More, duties 2 and 3 are not of the exclusive responsibility of the "using"
keyword :

   - typedef int id may be used to perform duty 2.
   - namespace bp = boost::process performs duty 3 for namespaces.

So, if we forget syntax, to what extent can we go berserk and break the
limitations of duties 1 up to and including 3, trying in the process to
stick to the following goals:

   - Make the extended behaviour consistent with the existing behaviour, to
   preserve teachability,
   - Make the extended syntax consistent with the existing syntax, to
   preserve teachability,
   - Be general,
   - Be orthogonal,
   - Break no code

?
